It will not sound mechanical. It will not sound like a recording studio monitoring tool, which DACs like Benchmark and D1 really are.
I have to disagree with this point. The D-1 is a very musical sounding DAC. The review I posted above is saying the same thing. I am listening to this DAC about 6 hours a day (like right now) and it is sweet and detailed. Just a unicorn DAC.
